Near Threshold

The data for near-threshold cross section for the reaction pp → ppɸ published by the DISTO and ANKE Collaboration are analyzed in order to evaluate the OZI ratio at low energies by taking into account corrections from the kinematics and the final-state interaction. Combining these new data with the few measurements available at higher energies the limit for the OZI rule violation is evaluated and the possible contribution from a five-quark baryonic resonance coupled to the ɸp system is estimated.

Transverse Momentum Spectra

The differential cross-section in squared momentum transfer of ρ , ρ 0 , ω , ϕ , f 0 980 , f 1 1285 , f 0 1370 , f 1 1420 , f 0 1500 , and J / ψ produced in high-energy virtual photon-proton ( γ ∗ p ), photon-proton ( γ p ), and proton-proton ( p p ) collisions measured by the H1, ZEUS, and WA102 Collaborations is analyzed by the Monte Carlo calculations. In the calculations, the Erlang distribution, Tsallis distribution, and Hagedorn function are separately used to describe the transverse momentum spectra of the emitted particles. Our results show that the initial- and final-state temperatures increase from lower squared photon virtuality to a higher one and decrease with the increase of center-of-mass energy.

D Wave

The final state interaction in the processes [Formula: see text] and [Formula: see text] close to the threshold is discussed. It is shown that, due to the Coulomb interaction, the contribution of the d wave to the cross section does not vanish even at zero relative velocity of produced particles. This results in the nonzero anisotropy in angular distribution at the threshold. We use the Paris nucleon-antinucleon optical potential for explanation of experimental data in the process [Formula: see text] near threshold. It follows from our consideration that the isoscalar form factor is much larger than the isovector one.

Incoming Nucleon

We investigated three-nucleon (3N) force effects in the final state interaction (FSI) configuration of the d (n,nn) pd(n,nn)p breakup reaction at the incoming nucleon energy E_nEn= 200 MeV. Although 3N force effects for the elastic nucleon-deuteron scattering cross section at comparable energies are located predominantly in the region of intermediate and backward angles, the corresponding 3N force effects for the integrated FSI configuration breakup cross section are found also at forward scattering angles.
